Timing control of VLSI based nlogn and crossbar networks
Sanjay Dhar, Mark A. Franklin, Donald F. Wann · Proceedings of the International Conference on Parallel Processing · 1983
Two basic data flow control methods for circuit switched, pipelined networks of the general nlogn and crossbar (cb) topologies are modelled and their effects on overall data rates achievable are determined. The synchronous method uses a global clock and as network modules grow, clock skew and clock tree charge/discharge times grow resulting in lower data rates. The asynchronous method relies on local request/acknowledge signals to control data movement and hence its performance is less affected by system growth. 12 references.
